Game developers may find PlayStation 3 development a bit more attractive today, thanks to the generosity of Nvidia. The graphics chip manufacturer is offering its PhysX tech to developers as a free download.

Nvidia, which also happens to be responsible for the PS3's RSX 'Reality Synthesizer' graphics chip, has inked a deal with Sony Computer Entertainment to provide the software development kit to PlayStation developers. That doesn't necessarily mean you're going to see above and beyond physics engine support on par with PhysX hardware acceleration, as in the Games For Windows version of Mirror's Edge, it may mean better things bouncing off other things in your PS3 library.
